“For a medical device manufacturer such as Cogent Technology, traceability of sub-assemblies is vitally important to both the client and the internal Cogent QMS processes.”
Paul Harrison-Rowe, Cogent Technology Engineering Manager.
Background
Established in 1985, Suffolk-based Cogent Technology manufactures cutting-edge medical devices and instrumentation for industry.
A trusted global leader in MedTech, GreenTech, and key sectors like telecoms, diagnostics, security, industrial, instrumentation and control; Cogent Technology occupy a pioneering 80,000 sq. ft. facility with two Class 7 cleanrooms and a 7,000 sq. ft. biological room.
With one of the largest smart factories in Europe, manufacturing for international distribution, Cogent Technology ensures all devices are produced to the highest quality standards and continually enhance their capital equipment investment to guarantee production runs effectively.
The Challenge
As technology advances, printed circuit boards (PCBS) are becoming smaller and more complex to manufacture. Therefore, it is important to have equipment and machinery to handle the shrinking size and density challenges.
With business continuing to grow, Cogent Technology was looking for a solution for the traceability of miniaturized PCBs.
“For a medical device manufacturer such as Cogent Technology, traceability of sub-assemblies is vitally important to both the Client and the internal Cogent QMS processes,” said Paul Harrison-Rowe, Cogent Technology Engineering Manager.
“At the moment, serial number labels are printed and fitted by hand. This was suitable for a low volume batch build process; however, this is now hindered by an ever-increasing demand for volume products, and an ever-decreasing size of printed circuit board and associated available space for labels.”
The Solution
Cogent Technology contacted Altus to discuss possible solutions that would address traceability. Following consultation, it was advised that the YJ Link YLM Laser Marker would meet the challenge.
As the production of highly advanced electronic assemblies increases, the importance of traceability has never been more important. High-tech manufacturers like Cogent Technology are looking for ways to implement processes to improve manufacture which can also integrate seamlessly into a ‘lights-out’ production plan. Aligning with these processes is the YLM Series Laser Marking solution from YJ Link.
Paul said: “In some circumstances, PCBs are either too small, or their specific operational requirements prohibit the use of serial labels. This meant that Cogent needed to find alternative solutions to:
“The solution to all of these problems was to invest in a Laser Marking machine that could internally flip over the PCBs and mark the same serial number to both sides, as well as speeding up the application time and reducing cost. Also, since the Laser Marker effectively reduces the size of the serial number real estate, a serial number could now be applied on PCBs where previously it was not possible.”
Meeting the Challenge
The YLM range addressed all of the challenges that Cogent Technology was facing. As one of the most affordable and technologically advanced laser markers available in the marketplace today, it is easy to operate and efficient with fast cycle times to ensure manufacturers meet high production targets with ease.
Integrating a top of the range Panasonic laser solution as standard, fiducial recognition, and an internal flipper, the YLM laser marker helps to achieve a 20% cost saving. There is also a keymark camera helping to prevent the wrong PCB from coming in and hold-down clamping to ensure the correct position is held to maintain marking distance and stop mis-alignment.
Once installed at Cogent Technology it will offer capabilities making it an ideal investment.
“The Laser Marker will allow some other new features to be introduced, such as marking the work order number onto the waste material of the PCB panel or having the ability to be able to mark logos, dates etc. as required,” said Paul .
Investing in Inspection
Cogent Technology made further capital equipment investments with the selection of an Optilia BGA Inspection System. With parts no longer available for their existing machine, the Optilia platform had the modular features that would fit in with the company’s demanding requirements.
Optilia Instruments’ high definition optical BGA inspection systems with its larger Field-of-View can see beneath low stand-off BGAs. It makes hidden balls and rows more visible to find micro-cracks, cold solder joints, whisker, scaling, excess flux and other soldering issues that high-priced X-ray systems cannot detect. In addition, the system features small optical probes and 5.0 megapixel digital image cameras to produce high-resolution pictures of the extremely low-clearance areas beneath BGAs, μBGAs, CSP and FlipChip packages.
Top-view attachable varifocal lenses with built-in LED lighting provide maximum inspection capability and offer flexibility in magnification, probe tip size and in lighting adjustment.
The Future
Joe Booth, Altus CEO said: “ Cogent has been a joy to work with on this project and it is brilliant news that they chose to partner with Altus Group Ltd and in doing so, have bolstered their product traceability and automation significantly. Cogent is a renowned player in medical device manufacturing sector where ensuring product quality is paramount and I am pleased that we can play our part with the YLM Laser marking series for YJ Link and the BGA inspection system from Optilia, both stand out processes from our portfolio. Optilia is the BGA inspection process's originator, and YJ Link is a market leader with its latest YLM laser marking capabilities. I hope this is a start of a long and fruitful partnership and look forward to seeing the units being implemented. ”
